Nike Triax 35 Black & Orange Blaze

Its a very distinctive design of watch today, and you can easily tell the maker by how it's designed.

The watch is by Nike, and you can tell it is one of their timepieces by the angled face and strap which comes from the opposite corners of the display. This model is one of their 35 lap running watches (the Triax 35 Regular line), and is designed for robust use in wet conditions (-it's 100m water resistant). This one has a catalogue number of WR0031-009 (the 009 is this colour combination Black/Orange Blaze)

As with most of the Nike LCD watches, it displays the time in very large easy to read digits (but with small seconds). There are two other lines above and below the time to show which time is used, and the day and date. It has dual time, alarm, chronograph (35 lap with split), lap data recall, and timer modes, along with a counter function (where a button press advances the count).

The back gives the model number as W620-4020, which suggests that the modules may have been made for Nike by Seiko. If that is correct, the serial number would show this as being made in 2003, which fits with the modules date function starting at 2000.

The back also says that this watch is under US patents D394391, D394391, D394391, and D394395.
